Hi, Ralf.

I have some good news and some bad news to report.

a cross-compiled LyX/Win 1.3.x runs beautifully on Windows, but only when I
use a natively compiled qt3.dll. If I try and use the cross-compiled
qt3.dll, then I get the dreaded popup "The application failed to
initialise itself correctly".

This is true both with a qt3.dll using the 'standard' linker options

QMAKE_LFLAGS            = -Wl,-enable-stdcall-fixup -Wl,-enable-auto-import
-Wl,-enable-runtime-pseudo-reloc

and when I add your script:

QMAKE_LFLAGS            = -Wl,--script,$(QTDIR)/mkspecs/cygwin-g++/i386pe.x-no-rdata
-Wl,-enable-stdcall-fixup -Wl,-enable-auto-import
-Wl,-enable-runtime-pseudo-reloc
